When a man is proud because he can understand and explain the writings of Chrysippus, say to yourself, If Chrysippus had not written obscurely, this man would have nothing to be proud of. But what is it that I wish? To understand Nature and to follow it. I inquire, therefore, who is the interpreter: and when I have heard that it is Chrysippus, I come to him (the interpreter). But I do not understand what is written, and therefore I seek the interpreter. And so far there is yet nothing to be proud of. But when I shall have found the interpreter, the thing that remains is to use the precepts (the lessons). This itself is the only thing to be proud of. But if I shall admire the exposition, what else have I been made unless a grammarian instead of a philosopher? except in one thing, that I am explaining Chrysippus instead of Homer. When, then, any man says to me, Read Chrysippus to me, I rather blush, when I cannot show my acts like to and consistent with his words.
